Sorry that I didn't make the problem clear. The type of printer isn't the issue. If you select a bunch of files in Windows Explorer and then click on File and Print, Win7 will print them all. If you print to a paper printer it prints one file per page. If you print to a PDF printer it creates a single PDF file with each of the original JPEGs in a separate PDF page. My problem is that Win7 appears to decide for itself which way up to print each JPEG. Even if they are all shown as right way up in Win Explorer they will be printed as portrait if the dimensions of the JPEG image are such that height is greater than width and as landscape if height is less than width. This is okay if printing on paper but when printed to PDF and then viewed on the screen some images are the right way up and some are sideways. It's a Win7 issue, not a printer one, and I would like to know whether I can turn this auto-rotate feature off. I can find ways around the problem but they are all tedious and messy.
